Newbie question about installation on w7

Hello,
I want to give a try qml and check it out.... but
I've downloaded sdk from a link http://releases.qt-project.org/qt4/source/qt-win-opensource-4.8.4-mingw.exe
i have error some might not work. And i did not work and my question is now: Is there any tutorial describing what i have to download and configure to make it work. For example nebeans was so easy install, create a new project, and compile.

What you've got yourself is not a SDK, it's just Qt libraries. You might need to get Qt Creator, too. Also, Qt libs you have are MinGW-based (compiled with mingw) but the compiler is not bundled in the package - you need to install it separately.

"i have error some might not work" - now place yourself in my position and try to answer that? How the heck should I know what you mean? You need to provide some concrete data (error code, error message, what happened, what were you trying to do etc.).

Yes i install all qt lib qt creator and MinGW 5.1.6.
Now i can create qml project but i cant 'compile' it is there any more i should do ?.
Or maybe some install order?
I did:
1 qt creator
2 MinGW 5.1.6
3 qt libs

Would be better to install QtC last, but that does not really matter now. Open Qt Creator, go to Tools->Options->Build & Run->Qt Versions and check if your Qt version is there. If not, add it (you need to browse to where qmake binary is). Also, check if compiler was detected.

In qt version i have auto on qt 5 beta but i uninstall it and add manually qt.4.8(in my case it's c:qt\4.8.4\bin\qmake.exe). On compilators i have mingw(C:\MinGW\bin\mingw32-make.exe?? no idea is it right) and gcc (C:\MinGW\bin\gcc.exe).
Still i don't see compile options as active any think else ?

Still in design view:
@
import QtQuick 1.1

Rectangle {
width: 100
height: 62
}@

i see results when i change some think. But i cant debug or build project.

ok, i have no idea were Project pane is and how to check any directions ?
Also when i open example project i can debug it and i can debug simple 'hello' my project, but when i close sample i cant debug my project?

i finally after some break know whats i did wrong. I did single file not project that's why i don't have build option. Still i made compiler C:\MinGW\bin\mingw32-c++.exe but seems not working. Any think more i need to do ?
